Magnetic drive pumps or Mag drive pumps use a magnetic coupling to transmit torque to an impeller thereby keeping the wet end of the pump and motor as two separate contained parts. A set of magnets is driven by a standard electric motor and in turn, the magnets drive the inner rotor and provide torque to the coupling. Magnetic drive pumps can be used in a variety of ways, including in corrosive chemicals and solutions. They are typically ideal for the circulation of mildly corrosive acids, alkalis, solvents, brine, plating solutions and other mildly corrosive chemicals and solutions that are compatible with the pump's material of construction.
